Jika Ra= 50 Rb=20 Rc=10 Jika roda a memiliki Va = 1 m/s tentukan kecepatan sudut roda c.

Diketahui :
Ra = 50
Rb = 20
Rc = 10
Va = 1 m/s

Ditanyakan :
ωc = .... ?

Penyelesaian :
Va / Ra = Vb / Rb
1/50 = Vb / 20
1 × 20 = 50 Vb
20 = 50 Vb
Vb = 20 / 50
Vb = 2/5

Vb / Rb = Vc / Rc
2/5 × 50 = Vc / 10
20 = Vc / 10
Vc = 20 × 10
Vc = 200

ωc = Vc / Rc
ωc = 200 / 10
ωc = 20 rad/s
